Thump of snow here too before sleet? Sounds just like 00z. Marginal..maybe can hang on to snow a bit longer

You might get a couple hours of heavy snow if lucky...its close for N CT. I'd feel better if I was in Union. It looks like more sleet though for N CT rather than much icing threat on the Euro.

Yeah I agree. Not sure south of HFD. Hard to say based on the maps I can look at.

Euro doesn't give much help to the BOS-ORH corridor...its a marginal sleet/snow profile at 18z tomorrow in which 0.50" of qpf has fallen the previous 6 hr.

LOL, at least it held steady.

I'm still torn about how much snow I'll get in the morning. I could see a several hour thump, but that sneaky warm layer ruining the party is in the back of my mind. Those high level warm tongues always like to shoot in a little quicker than we think. However, if it's something near 0C or even like 0.5C for 50mb, perhaps the vv's can offset this.

Hey Will (know your busy)

Just wondered what your thoughts were regarding tonight into tomorrow morning, looks like there is a pretty large break between whats falling now and the swfe tom. Do you think we get persistant zr drizzle like i have now down this way or do you think precip shuts off totally, also are you thinking we stay zr rain tomorrow, I have a hard time seeing temps budging at the surface with HP to our north and a nice northerly drain.

Thanks if you have the time.

He was probably reporting rimed snowflakes mixed in with regular ones....they will look like normal snowflakes frequently but you can def hear them when they hit as they have just a little bit of ice in them.They aren't sleet pellets so vis can stay pretty low.

^^^This

Although, definitely ip/sn now....very strange. Vis is still really low (1/2 to 1/3 mile), but the woods sound like it's all sleet.

For crude map viewing, I've found that the +3 850 isotherm is pretty decent for sleet vs ZR...it can obviously vary depending on where the warmest layer is and how intense, but I've found that to be a quick crude tool.

Sam, how far north do you think the prolonged sleet session gets? I'm about 3mi N. or RT 2. / I-91 intersection.

At least up to rt 2. You'll definitely have to deal with a few hours of it (like 10a or 11a to 1p), but might escape the worst, and will definitely get a good dumping of snow beforehand (7-10" on top of today)

Yeah I use about the same but still hard to tell on my WSI euro maps. But it is on the colder side of guidance that woul dbe more PL than ZR.

Id take a nice 6" thump even if sleet after that. That could end up being like 13-14" when adding in today. So when does the euro start the snow again? around 9z or later?

BTW still mod snow here but slowing up a little...looks like were done by 3-330.

Yeah no doubt about that. Its def more of an IP look for probably northern 2/3rds of CT IMHO just looking at it quickly. S CT in those towns near rt 15 are def in for an icing event probably no matter which piece of guidance you take.

So can you give me any tips on how to deal with an epic storm from first hand experience? Not good at all!

Joe,

Looking upstream there's def a lot of places reporting light ZR and such where there are no echoes....so I wouldn't be surprised to see a lot of freezing drizzle, but the precip could shut off totally at times. It should be interesting...I think the precip early tomorrow comes in pretty quickly...it might be into a lot of the region by 09z.
